This is the most I've seen of him today and he never did grab that piece of cereal:
Update: I got tired of waiting and therefore tricked him a little bit...
Step 1: find egg carton, cut holes, place asparagus on top.
Here he is eating asparagus!
Step 2: being a hamster, he found the egg carton super exciting and climbed in.
Step 3: grab egg carton containing hamster and place in travel cage. Move person and hamster to hamster-escape-proof bathroom.
Commence handling experience.
He's adorable. I kind of doubt he'll climb into the egg carton again now though...
